Abstract
We report a new method for protecting nucleosides for hydrogen phospho nate RNA synthesis that gives very high yields for the purines. This m ethod is based on our finding that, for adenosine and guanosine, silyl ation of a mixture of 2' and 3' H-phosphonates in the presence of DBU is highly selective for the 2' hydroxyl.
